Detailed Description
Example 1
As shown in FIG. 1, the energy-absorbing mobile phone rear shell provided by the utility model comprises a shell 1, wherein the shell 1 comprises side edges 11, a top edge 12, independent corner blocks 2 and a back plate;
the four corners of the shell 1 are provided with matched independent corner blocks 2;
the side edge 11, the top edge 12 and the independent corner block 2 are combined to form a middle frame; the backboard and the middle frame are combined to form a shell 1 of the mobile phone; the mobile phone display screen, the battery and the main board are all arranged in the shell 1;
the independent corner block 2 is arranged in a circular arc shape and is used for connecting the side edge 11 and the top edge 12;
the independent corner block 2 is fixedly connected with the side edge 11 and the top edge 12 through an adhesive.
In this embodiment, the side edges 11 and the top edge 12 are provided with at least one layer of adhesive; the adhesive is elastic adhesive; meanwhile, the contact surfaces 3 of the side edges 11 and the top edges 12 of the shell 1, which are connected with the independent corner blocks 2, are polished to be rough, the surfaces of the corresponding independent corner blocks 2 are polished to be smooth, and the contact surfaces 3 of the corresponding independent corner blocks with the side edges 11 and the top edges 12 are polished to be rough;
when the independent corner block 2 is assembled with the shell 1 by using the adhesive, the contact surface 3 can obviously increase the contact area with the adhesive due to rough polishing, so that the adhesive force is increased, and the independent corner block 2 is not easy to fall off in the daily use process; when the mobile phone accidentally falls, the stress of the independent corner block 2 is smaller than the adhesive force of the adhesive, so that the adhesive is stressed and deformed to buffer, and the impact on a screen is reduced; when the stress of the independent corner block 2 is larger than the adhesive force of the adhesive, the independent corner block 2 is separated from the adhesive and falls off from the casing 1, so that part of energy generated by falling is taken away, the extrusion energy of the mobile phone main body is reduced, and the mobile phone is protected.
Example 2
The utility model provides an energy-absorbing mobile phone rear shell, which comprises a shell 1, wherein the shell 1 comprises side edges 11, a top edge 12, independent corner blocks 2 and a back plate;
the four corners of the shell 1 are provided with matched independent corner blocks 2;
the side edge 11, the top edge 12 and the independent corner block 2 are combined to form a middle frame; the backboard and the middle frame are combined to form a shell 1 of the mobile phone; the mobile phone display screen, the battery and the main board are all arranged in the shell 1;
the independent corner block 2 is arranged in a circular arc shape and is used for connecting the side edge 11 and the top edge 12;
the independent corner block 2 is fixedly connected with the side edge 11 and the top edge 12 through an adhesive;
the contact surface 3 between the top of the side 11 and the independent corner block 2 is an inclined surface; the contact surface 3 is low on the side facing the outside of the casing 1 and high on the side facing the inside of the casing 1.
The contact surface 3 between the side surface of the top edge 12 and the independent corner block 2 is an inclined surface; the contact surface 3 is low on the side facing the outside of the casing 1 and high on the side facing the inside of the casing 1.
Because the contact surfaces 3 of the side edge 11 and the top edge 12 of the shell 1 are inclined surfaces, the contact surface 3 is low towards one side of the outer part of the shell 1 and is high towards one side of the inner part of the shell 1; after the independent corner block 2 is installed with the shell 1, the mobile phone accidentally falls, when the stress of the independent corner block 2 is larger than the adhesive force of the adhesive, the independent corner block 2 can be better separated from the adhesive, and falls off from the shell 1, so that part of energy generated by falling is taken away, the extrusion energy of the mobile phone main body is reduced, and the mobile phone is protected.
